I installed Steam from the Lite Software  tool - it wouldn't launch . I read several threads etc. - uninstalled from  Lite Software tools and  installed  only the  launcher  in synaptic - still won't  launch . Here  is  my output from the terminal

I had a great deal of trouble  previously when I installed  nvidia  drivers  in a  previous distro ; totally frapped  my whole system . Could someone  offer some advice  on which , if any  of these drivers  I should  install ; or , is there some  other explanation why I'm having  trouble installing steam ?        If I install 1 of these others in place  of the x.org Nouveau driver will steam then find it's way to them  ?    As far as I can see all  the noveau  dependencies are met
                             
                                                  thanks all
